Add support for reading slices of text files.
Incrementing version to 2.3.0 final
Typo.  Missed index.html in incrementation
Fixed CB-2089 after I tagged for the release.  This will have to sit in 2.4.0
And support for slicing in readAsDataURL.
Merge branch 'master' of https://git-wip-us.apache.org/repos/asf/cordova-android into file_slicing
